MANUFACTURE OF CIGARS Application March 18, 1936, Serial No. 69,443 InGermany March 21, 1935 9 Claims.

This invention relates to the manufacture of cigars by machinery, andmore particularly to the manufacture and application of the outerwrapper.

An object of this invention is to provide a device'which may be usedwith a wrapping machine which initially cuts the Wrapper into thedesired shape and then applies an adhesive to at least one end of thewrapper as it is being fed to the wrapping machine.

Another object of this invention is to provide animprovedtype of wrapperwhich is so constructed that it will smoothly engage the fillerand-which embodies a construction which will permit the smoothapplication of the wrapper at the mouth end of the cigar irrespective ofwhether or not the wrapper is initially started at the proper point withrespect to the filler.

A further object of this invention is to provide 20 a device which isadapted to stamp out the wrapper'in the desired shape and then transferthe shaped wrapper to the wrapping machine, at least one end of thewrapper being supported for engagement'with an adhesive applying meansso that the flag end of thewrapper will be secureiy held about thefiller.

With the foregoing and other objects in view, the invention will be morefully described hereinafter and will be more particularly pointed out 30in the claims. appended hereto.

Figure 7 is an enlarged vertical section of the punch.

Figure 8 is a sectional view taken on the line 8-8 of Fig, 4;

Figure 9 is a fragmentary end elevation of the wrapping machine andincluding the adhesive applying means shown in Fig. 8.

Referring to the drawings, and first to Fig. 1,

the letter a designates generally the body of an elongated wrapperhaving an angularly related flag end 17 which is semicircular as shown,and which is provided with a radial slit 0. The idea of using a slitsuch as the slit 0 will work satisfactorily where the filler is placedon the'filler wrapping means with precision, but as there is frequentlya variance in the. disposition of the filler on the filler wrappingmeans, where a wrapper is used similar to that shown in Fig. l the flagend of the wrapper usually becomes, very much distorted and folds appearat the mouth end of the cigar. The wrapper for the cigar is usuallymoist and on account of this condition the wrapper will more readilybecome distorted during the wrapping operation, and as a slight variancefrequently occurs in the initial application of the wrapper, a wrapperof the type shown in Fig. 1 is not conducive to a smoothly wrappedcigar.

In Figure 2 there is shown a wrapper of substantially the sameconfiguration as the wrapper shown in Fig. 1, but having a differentshaped incision than that shown in Fig. 1. In Fig, 2

a central round hole at is provided, and from this n two diverging cutouts form with the round hole a slot 0', as shown in Fig. 2. Thesediverging incisions form a trapezoidal portion, and this trapezoidalportion forms with the circular portion 0! of the round hole the slot0'. The use of a wrapper of this type will allow for any slightvariations in the initial application of the wrapper to the filler byreason of the misplacement of the filler with respect to the wrappingmeans.

The wrapper (2" shown in Figure 3 is somewhat. similar to the wrappershown in Fig. '2, except that the flag portion b" thereof is providedwith a slot e having parallel sides and ending in a rounded inner endabout the axis of the flag b".

The material from which the wrapper a, or the wrapper a" is made ispassed overa table 2 which is provided with a knife 4 having theconfiguration of the wrapper a, and inside. the knife a suction head 3is provided for retaining the formed wrapper on the table 2 while thewaste. material is being removed.

Having initially formed the wrapper a without the slot or hole in theflag end thereof, the wrapper a is removed from the table 2 by means ofa carrier 2| which is connected to a source of air suction. The carrier2| is mounted on a standard or base for horizontal swinging movement,and at the time that the carrier 2! isin position to pick up theformed'wrapper a, the suction to the head 3 is out 01f, or it may bereversed so as to forcibly discharge the formed wrapper onto the underside of the carrier 2|.

When the wrapper a has been picked up by the carrier 2|, the carrier isthen swung to the left as viewed in Fig. 4 and as indicated by the dotand dash lines o. The flag end b of the wrapper a is positioned with thecenter thereof directly above a punching member 5 which is secured to anarm 6 carried by the upper end of a vertically movable shaft 8. The arm6 has a split eye portion 6 which is detachably clamped onto the reducedupper end of the shaft 8 by means of a screw 1. As shown in Figs. 5 and6, the shaft 8 is slidable in. a guide 9 carried by a base G, and anoutstanding pin I0 is secured to the shaft 8 intermediate the endsthereof and above the top of the guide 9. The forked end H of a lever |2engages the pin I0, and the opposite end of the lever I2 is mounted on apivot l3 carried by a bracket arm M which is fixed to the guide 9.

A drive shaft 20 is rotatably supported on bearings 20 carried by thebase G, and this shaft 20 has a punch lifting member l6 secured theretowhich has a lifting cam 22 at one portion thereof. The lever |2 has aroller |5 on. the lower side thereof which is adapted to engage theperiphery of the lifting member and the cam 22. The roller I5 ismaintained in contacting relation with the lifting member l6 by means ofa spring l8, one end of which is secured to a pin carried by the lever.l2, and the other end of which is secured to a pin l9 carried by theguide 9. The major portion of the lifting member H5 is disposedconcentric to the axis of the shaft 20 so that during this cycle of thelifting member l6 the shaft 8 carrying the punch 5 will remainstationary, and when the roller I5 is engaged by the cam portion 22 thelever I2 is raised and the shaft 8 with the punch 5 is also raised.

The under side of the carrier 2| may be provided with a cushion 23against which the upper end of the punch 5 may engage. The punch 5 ishollow, and as shown. in Fig. '7 the interior is mounted between rollersdownwardly flared so that the cuttings of the wrapper may easily falldownwardly, or if desired a suitable suction means may be attached tothe lower end of the punch 5 so that the cuttings may be carried by suchsuction means to a suitable point of discharge. In horizontal sectionthe shape of the punch 5 is similar to the tapered slot 0 and theopening d, shown in Fig. 2.'

After the flag end I) has been properly slotted by the punch 5, thecarrier 2| is moved, as by swinging, to the position shown at w in Fig.4. In thisposition the end of the wrapper a which engages the outer endof the filler is disposed in a position directly above the filler Zwhich is Also, as shown in Fig. 4, the direction of movement of thewrapper is shown by the arrows at and'yn The other or flag end of thewrapper a is disposed above an adhesive applying roller 24 which ismounted on a shaft 25. The shaft 25 is mounted on one arm of a bellcrank 26, and a roller 30 is mounted on the end of the other arm of thebell crank 25. The roller 39 engages a cam 3| which is secured to theshaft 20 so that when the carrier is in adhesive applying position theroller 24 will engage the under side of the wrapper.

An adhesive transfer roller 29 which is mounted on a shaft 21 ispartially submerged in a reservoir 28 which is adapted to have asuitable adhesive disposed therein. -A driving gear 32 is secured to thedrive shaft 20 and engages a driven gear 33 mounted on a shaft 34, and agear train including the gears 33, 36, 31 and 40 will rotate thetransfer roller 29 and also rotate the adhesive applying roller 24, thelatter roller being rotated at substantially the same speed as thelinear movement of the wrapper a about the filler Z. The roller 24 alsorotates in the direction of the movement of the wrapper as it is beingwrapped about the filler Z so that the roller 24 will not effect anydistortion of the shape or size of the wrapper a. i

In the use and operation of this device, the blank wrapper is initiallystretched across the table 2 and over the forming knife 4. A roller orother pressure means is then applied to the upper surface of the blankwrapper so as to cut out the wrapper which is then held in position bythe suction'device 3. When the wrapper has been properly shaped as toits marginal configuration, the carrier 2| is brought into overlyingposition to the head 3 of the table 2, and at this time the suction. ofthe head 3 is cut off, or if desired the suction may be reversed so asto eject the formed wrapper from the cutter 4. The suction in the head2| will retain the formed wrapper on the underside thereof, and then thehead 5.:

2| may be swung to the punching position where the. cushion 23 willoverlie the punch 5. At this time the cam 22 will be disposed in aposition to engage the roller I5 and thus raise the lever l2 togetherwith the shaft 8 and the punch 5.

The punching operation is performed quickly, and then the carrier 2| ismoved to the adhesive applying position, and at this time the suction ofthe carrier 2| may be cut off so that the outer end of the wrapper awill engage the filler Z. l

As soon as the carrier 2| is in adhesion applying position, the cam 3|will be so disposed that the lower end of the bell crank 26 will swingin the direction of the shaft 20 and thus carry the upper end thereofupwardly toward the overlying cari The adhesive applying roller 24 isse-' rier 2|. cured to the upper end of the bell crank 26 so that whenthe upper portion of this bell crank rises the roller 24 will come intocontact with the underside of the wrapper a. flag end of the wrapper ais engaged by the roller 24.
